PortAudio is a portable audio I/O library designed for cross-platform
support of audio. It uses a callback mechanism to request audio processing.
Audio can be generated in various formats, including 32 bit floating point,
and will be converted to the native format internally.

Documentation:
	See "pa_common/portaudio.h" for API spec.
	See docs folder for a tutorial.
	Also see http://www.portaudio.com/docs/
	And see "pa_tests/patest_saw.c" for an example.

For information on compiling programs with PortAudio, please see the
tutorial at:

  http://www.portaudio.com/docs/pa_tutorial.html
